摘要
In order to localize olfactory-based searching mobile robots in the indoor environments, a monocular-vision localization algorithm was proposed based on least square support vector machine (LS-SVM) method. By using Gaussian kernel LS-SVM classifier, the non-linear mapping between robot real positions to pixels in the image could be translated into linear mapping with Gaussian kernel. Then, k-fold cross validation was used to seek the optimized parameters after linear mapping model training. Finally, continuously moving robot was identified based on greyscale level in real time from sequential images reordered by a single camera. The real-time position of robot in the indoor environment was calculated from the vehicle's geometric center pixel on every image using the linear mapping model developed herein. Experiment results show that the proposed localization algorithm can provide high precision real-time position information for robots in the indoor environment without error accumulated with time. The accuracy and reliability of the algorithm were fully verified. © 2019, Editorial Board of Journal of Huazhong University of Science and Technology. All right reserved.
